PRESSURE-REGULATQR FOR GAS BURNERS.

SPECIFICATION forming part of Letters Patent No. 392,489, dated November6, 1889.

Application filed March 3, 1888.

To aZZ whom it may concern.-

Be it known that I, ORSON W. BENNETT, a citizen of the United States,residing at \Vash ington, District of Columbia, have invented certainnew and useful Improvements in Pressure -Itegulators for Gas-Burners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in gas-pressure regulatorsespecially applicable to single or separate burners in which two or moreopposing currents tend to neutralize the excess of pressure required tomaintain a proper city service.

Two or more passages in opposition to each other leading to a singlepassage cause the parts of the divided current to impinge against eachother, and the flow is thus retarded in proportion to the pressure orforce of the branches of the current. An approximately constant pressureis thus obtained and maintained at and beyond the junction of theopposing branches, notwithstanding the fact that the pressure frombehind may vary to a considerable extent.

Theinvention consists in an automatic check or regulating plug forgas-burners provided with axial passage at one end, an annular reductionor passages along the periphery at the other end, and centripetalpassages opposite each other leading from the peripheral passages to theaxial passage.

In the drawings forming a part of this specification, Figures 1 and 2are sections of a gasburner complete with my invention applied thereto.Fig. 3 is a check in elevation showing passages along the sides leadingto the centripetal passages. Figs. 4 and 5 are sections of differentforms of check to be inserted within the pillar.

A is the pillar, and B is the tip of an ordinary gas-burner, whichtogether constitute a complete burner.

C is myimproved automatic check-plu g havin g an annularly-reduced endor side channels, 0 c, the centripetal passages c c,and the axialpassage 0. This check-plug is slightly conical at one end and of a sizeto be inscrtedinto and removed from the interior of the pillar.

It may be made integral with or be attached to the tip, as shown in Fig.1 of the drawings,

pillar.

It should be observed that as the cheek part of the burner regulates theamount of gas to be consumed, relatively large tips should be used withit. A greater amount of light is obtained with a given amount of gas inthis way than would otherwise be the case, because in a city servicethere must be a pressure in excess of the best conditions in order thata large number of consumers may be fully supplied. This check-plug beingdetaehable,may be removed from the pillar for the purpose ofcleaning,for the purpose of being replaced by another of differentcapacity,or to convert the whole to the ordinary form of burner asoocasion may require or judgment dictate.

In practice I make the lower end of the check only slightly smaller thanthe body part; but that there may be a full supply of gas to thecentripetal passages I make an annular groove around the plug leadingdirectly to the mouth of the said passages.

I do not claim,broadly,a burner or pressureregulating device providedwith opposing passages, nor do I claim a removable cylindricalcheek-plug made to fit the inside of the burnerpillar; but

WVhat I do claim is- The combination, with the ordinary pillar of agas-burner, of a pressureregulating plug made to fit inside anddetachably connected with said pillar, the plug being provided withpassages along the sides at one end, an axial passage leading from theother end, and opposing or centripetal passages leading from the outsidepassages to the axial passage,said centripetal or opposing passagesleading to ward one another to a point where the jets of gas issuingtherefrom will impinge directly against one another, substantially asdescribed.

In testimony whereofI alfix my signaturein presence of two witnesses.
